I’m not the author, but:
No one owes anything to anyone - this is the starting point of a relationship. And then there are common affairs and the following of them are obligations and agreements.

You guys, everything remains the same. The whole feature of human relationships is precisely in the degree of sincerity. If sincere desires and emotions are lacking, people begin to replace them with a sense of duty. They are not happier from this. Agreement in such things as caring for each other, creating a cozy home, and so on – all this should be based on love and empathy. Obligations are only those stipulated by law. Children up to the age of 18 are kept there, joint income is shared in case of divorce, etc. There should be no more obligations. No matter how upset you are that your feelings are not respected, that they don’t care about you, that they don’t wash your dishes, that they don’t give you gifts and don’t want to have sex with you – no one owes you anything. Be offended, argue as you like, but do not scream about obligations, because they are not obligations. And the sooner people begin to realize this, the more chances they have for real happiness in life.
